343 Industries has updated Halo: The Master Chief Collection again, further fixing numerous multiplayer issues and adding Halo 4's Spartan Ops mode. Spartan Ops is a multi-mission episodic co-op mode that launched over the course of several for Halo 4.

"The next time you log into Halo: The Master Chief Collection, you will be prompted to download the latest content update," said 343. "This particular content update includes improvements for matchmaking, roster, custom games, and adds Halo 4’s Spartan Ops mode. Below, you’ll find a summary of the updates that are included in today’s update."

In addition to this, the studio added that, "We’ve seen many inquiries about dedicated server support for Halo: The Master Chief Collection. Dedicated servers have been up and running since launch, and we continue to optimize and improve connectivity."

"The vast majority of games are being played on dedicated servers, but in the event that players cannot connect to a dedicated server, the lobby will stay together and the match will still occur on a peer-to-peer connection."

"Please be aware that you may connect to the dedicated server quickly enough that you won’t see the ‘connecting to dedicated server’ dialog. The absence of that dialog doesn’t mean that you’re not playing on a dedicated server."
